WHEEL SPECIALLY ADAPTiED TO RECEIVE AN AUXILIARY OR SPARE RIM.

Patented July 28,1908.

To all whom it may concern:

Be it known that I, THOMAS MORRIS DAVIES, subject of the King of GreatBritain,

residing at Llanelly, in the county of Carmarthen,Wales,England,haveinventedanew and useful Wheel Specially Adapted to Receivean Auxiliary or Spare Rim, of which the following is a specification.

Heretofore spare rims, each carrying a fully inflated tire, have beenattached to the rim ofa wheel fixed to a motor car, hereinafter referredto as the fixed wheel, by hooks or other means which grippedthe outeredge of the metal rim of the fixed wheel. In such a method ofattaching sare rims it has been necessary to push the e ge of theouter cover of thepneumatic tire laterally to enable the spare rim to be properly attachedto the fixed wheel, and such outer edges occasionally are veryfirmly'embedded in the-rim. If, to pre-" vent skidding or for otherreason, it has been desired to fix la spare rim to a fixed wheel havingan unpi nctur ed tire, it has also been necessary to deflate thepneumatic tire of the fixed wheel to enable the said edge to be movedlaterally away from the side of the IlIIl.

The object of the present invention is to construct the fixed wheels insuch a manner I that a spare rim carrying a pneumatic tire may always bereadily applied thereto. It is thus possible toattach a spare rimcarrying a fully inflated tire of: any type to a fixed wheel having apunctured tire, and it is also possible to rapidly apply a spare rimcarrying a non-slipping tire to a fixed wheel having an unpuncturedsmooth pneumatic tire without deflating this latter.

According to the present invention the fixed wheel is provided withacontinuous extra flange on its outer face ontowhich the spare rim may besecurely fastened by means of the usual hooksand other devices alreadyknown. Or in lieu of a continuous extra flange, a number of separatedportions of said flange may be employed, each portion being somewhat inthe form of a hook or loop. This extra flange ispreferably of such adiameter that it is close to the metal rim of the fixed wheel and itispreferably so located and of such width that it does not project lat-When applied to a wheel having only a metal rim, the extra flange isconveniently formed on a cylindrical ring which is riveted or otherwisefixed to the flat portion of the fixed metal rim.

, When applied to a wheel having a wooden felly surrounded by a metalrim the extra flange is conveniently formed on aflat or slightly conicalring which is bolted to the wooden felly, in which case the bolt headsor nuts-may be provided on the inner side of thefixed wheel with largeWashers to distribute the strain over a large area of the felly. In thislatter construction'the flange may be formed on either edge of the flator conical ring, that is to say, on the edge which is nearer to orfarther from the hub of the fixed wheel. v v y a The so-called flangeattached to the fixed wheel may conform to the shape of one edge of anordinary metal rin'r adapted to receive a pneumatic tire, or it may beof. any other suitable section, according to the kind of fixing meanscarried by the spare rim i Should the wooden felly be of such a sec:tion that the flat or slightly conical ring carrying the flange cannotbe securely fastened thereto by means of bolts and nuts, it may benecessary to em loy distance pieces placed between the said flat orslightly coni ical ring and the wooden felly, which distance pieces maybe secured by the bolts used to .attach the said ring to the wooden'felly.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of part'of a fixed Wheel, and Fig. 2 is anedge view partly in section' showing an ordinary spare rim adapted tocarry an'inflated pneumatic tire and the fixed wheel shown in Fig. 1 towhich such spare rim is attached; Fig. 3 is a cross section through thefelly of the said fixed wheel; Fig. 4 is a cross section of a felly of afixed wheel very similar-to that shown 'in Figs. 1, 2 and 3. Fig. 4 alsoshows cross sections of other forms of flanges of somewhat differentshapes. In all these figures the extra flange is bent outwards away fromthe hub. Fig. ,5 shows a cross section of a felly of a fixed wheel inwhich the extra flange is side elevation of part of a spare rim similarto that shown in Fig. 5. Fig. 7 is'a side elevation of a plate carryinga portion of an extra flange; Fig. 8 is a side elevation of part of theclip carried by a spare rim adapted to engage with the extra flangeshown in Fig. 7; Fig. 9 is a side elevation of the parts shown in Figs.7 and 8 acting in conjunction with each other. Fig. 10 is asideelevation of part of a fixed wheel having a portion of an extra flangein the form of a loop; Fig. 1 1 is a side elevation of the usual hookfastening adapted to engage the loop shown in Fig. 10, and Fig. 12 is asideelevation of the parts shown in Figs. 10 and 11 acting inconjunction with each other. Fig. 13 is a cross section of an ordinarymetal rim such as is used with wire spokes with an extra flange applied'thereto. Fig. 14 is a cross section of a metal rim and wood fellyin which the two sides of the latter are not parallel to each 1 other,with an extra flange applied to such section carried by felly. Fig. 15is a cross section of a metal rim and wooden felly showing anothermethodof fixing the extra flange. Fig. 16 is a cross section of a metalrim as wire spokes showing the extra flange applied thereto inasimilarmanner to that shownin Fig. 15. v

Referring to Figs. 1 to 3, a is the usual rim adapted to receive apneumatic tire and fixed around the wooden felly b. c is an extracontinuous flange of trough shape in cross a flat ring 0', and havingits outer edge presented outwardly or away from the hub b of the fixedwheel. The flange c and ring 0 are rolled or otherwise formed in onepiece. This extra flange c is secured to. the outer face of the woodenfelly b by bolts (1. assing through the ring c and the'felly an held inposition by nuts (1. The spare rim e is of the usual construction butits hook shaped cli s e, instead of engaging with the edge oi. the rima,'engage with the continuous extra flanges.

Fig. 4 shows various sections of extra continuous flanges 0 adapted tobe bolted to the wooden felly b. It will be noticed that the flat ortiona through which the headed ends of t e bolts d'pass, projects towardsthe hub,

I whereas in Figs. '1, 2 and 3 it projects away 2 from the hub. In thisview large washers are shown between the nuts. (1 and the wooden felly bto distribute the strain over a large area. The wooden felly is usuallyof less width than the width of its metal rim, which enables the flangeto be arranged so that it does not project laterally beyond said metalrlm.

In Figs. 5 and 6 the extra flange c is bent over towards the hub of thefixed wheel and the radially moving parts e of the auxiliary rim 0 havetheir hook shaped parts e curved used with outwards away from the hub.In this construction the screws f have winged heads f and pass throughscrew threaded parts f carried by the auxiliary rim e. The screws fenter sockets in the radially moving parts 0 which latter are mounted inguides as usual.

In Fig. 7 the extra flange c is not continuous but consists of a numberof segments of a circle, each of which is carried by a plate 0 havingholes therein by which it may be bolted to a wooden felly. The radiallymoving parts or clips e? of the auxiliary rim for use with such an extraflange are preferably slotted as shown so as to pass over the segmentalflanges c. p

In Fig. 10 the segmental extra flange 0 projects laterally from theplate 0 in the form of a loop. It is actually part of the plate cf bentlaterally to receive the usual hooks e of an auxiliary rim.

The advantage of using the extra flanges 0 shown in Figs. 7, 9, 10 and12 and the special form of clip shown in Fig. 8 is that the auxiliaryrim e is prevented from creeping with relation to the fixed rim withoutthe use of a fork or strapto engage a spoke of the fixed wheel.

Fig. 13 shows a metal rim a to which an extra flange c is riveted. Inthis construction the extra flange c is fixed to a cylindrical ring 0which latter fits the interior periphery of the rim a and is rivetedthereto.

Some wooden fellies b, as shown at Fig. 14, have a wedge shaped section,that is to say, theinner and outer facesare v not. parallel. With suchfellies it is necessary to employ filling up or distance pieces 1)between the felly b and the inner side of the extra flange 0. Thesedistance pieces I) are secured by the b ilts d which attach the extraflange c to the fe l b.

Iii Figs. 15 and 16 the extra flange c is shown brazed or welded to themetal rim 0..
